DISTRIBUTION:

The Catocala grisatra moth (wingspan: 48-55mm) flies in the coastal plain in Bladen County, North Carolina, south through Georgia to Florida. Specimens have also been recorded in the southeastern sandhills region of coastal North Carolina.

The forewings of this moth make it look like a miniature ulalume.

The forewings are bluish grey with a darker anal dash and wide arc from the reniform spot to the outer margin.

The median band of the hindwing does not make a complete loop. This species is uncommon and very local in its limited range.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Catocala grisatra flies as a single generation with moths on the wing in May and June.

The Catocala grisatra caterpillar shows a preference for hawthorns.

ECLOSION:

Adults eclose from pupae formed under leaf litter.

SCENTING AND MATING:

Catocala grisatra females emit an airbourne pheromone and males use their antennae to track the scent plume.

EGGS, CATERPILLARS, COCOONS, AND PUPAE:

Eggs are deposited on tree bark in the fall and hatch the following spring.
